Struct FontTweak

pub struct FontTweak {
    pub scale: f32,
    pub y_offset_factor: f32,
    pub y_offset: f32,
    pub baseline_offset_factor: f32,
}

Extra scale and vertical tweak to apply to all text of a certain font.

Fields

scale: f32

Scale the font’s glyphs by this much. this is only a visual effect and does not affect the text layout.

Default: 1.0 (no scaling).

y_offset_factor: f32

Shift font’s glyphs downwards by this fraction of the font size (in points). this is only a visual effect and does not affect the text layout.

Affects larger font sizes more.

A positive value shifts the text downwards. A negative value shifts it upwards.

Example value: -0.2.

y_offset: f32

Shift font’s glyphs downwards by this amount of logical points. this is only a visual effect and does not affect the text layout.

Affects all font sizes equally.

Example value: 2.0.

baseline_offset_factor: f32

When using this font’s metrics to layout a row, shift the entire row downwards by this fraction of the font size (in points).

A positive value shifts the text downwards. A negative value shifts it upwards.

Trait Implementations

impl Clone for FontTweak

fn clone(&self) -> FontTweak

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontTweak

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FontTweak

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FontTweak

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FontTweak

fn eq(&self, other: &FontTweak) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

where __S: Serializer,

Serialize this value into the given Serde serializer.
